The Santa Fe Institute does a considerable amount of innovative, state-of-the-art research on the interaction between different sciences and nature. This site is highly recommended for anybody interested in human/animal behavior, science, engineering, biology, mathematical modeling, philosophy and the interaction between these different areas. Let me know your thoughts about this broad topic.
If you are working in this area and would like to discuss ideas and concepts, I would be more than happy to meet with you.
The basic foundations of science will be changed this fall (September 2000). Stephen Wolfram's book, A New Kind of Science is expected to re-define how we think about the universe. Fields of science that are discussed include physics, mathematics, biology, computer science, among others.
